 # Changelog
 
+## 2026-02-02 - 3.42.0 - feat(dees-form-submit)
+forward button properties to internal dees-button, use property bindings, add demo and styles
+
+- Added forwarded properties: type, size, icon, iconPosition (with defaults) and preserved text/status/disabled
+- Changed template to use property bindings (.prop) for dees-button instead of string attributes
+- Switched internal event handler to listen for dees-button's @clicked event (was @click)
+- Added component styles (:host display and dees-button width:100%) and improved layout
+- Expanded demo with multiple usage examples (basic, icons, types, sizes, states, and a form context)
+
+## 2026-02-02 - 3.41.6 - fix(dees-simple-appdash)
+respect selectedView when loading initial view, falling back to the first tab
+
+- firstUpdated now loads this.selectedView if set, otherwise loads the first view tab
+- Prevents always loading the first tab and preserves a previously selected view on initial render
+
+## 2026-02-01 - 3.41.5 - fix(dees-service-lib-loader)
+prevent horizontal scrollbar by offsetting xterm WidthCache measurement container
+
+- Injects additional CSS into DeesServiceLibLoader to move xterm.js WidthCache measurement div off-screen horizontally (selector: body > div[style*="top: -50000px"][style*="width: 50000px"])
+- Fixes root cause where xterm creates a large-width measurement container (width: 50000px) on document.body that expands scrollWidth and causes a horizontal scrollbar
+- Change applied in ts_web/services/DeesServiceLibLoader.ts by concatenating the fix CSS into the injected stylesheet
+
+## 2026-01-29 - 3.41.4 - fix()
+no changes
+
+- No files changed in this commit; no code or documentation modified
+- No release required
+
+## 2026-01-29 - 3.41.3 - fix(dees-pdf-viewer)
+use in-memory PDF data for download and print; add robust print wrapper, cleanup and error handling
+
+- Download and Print now use pdfDocument.getData() to create Blob URLs so in-memory PDFs (pdf.js) can be saved/printed.
+- Print flow now opens an HTML wrapper with an iframe to allow onafterprint handling, auto-close, popup-fallback and timed cleanup of Blob URLs.
+- Added try/catch logging, URL.revokeObjectURL calls and safety timeouts to avoid resource leaks.
+- Removed context menu items that relied on the raw PDF URL (Open in New Tab, Copy PDF URL); Download/Print actions now await the async handlers.
+
 ## 2026-01-28 - 3.41.2 - fix(dees-pdf-viewer)
 account for devicePixelRatio when setting canvas dimensions and scale 2D context to render crisp PDF pages and thumbnails on high-DPI displays
